Texas and Oklahoma are slowly marching toward the United States Supreme Court (and probably a series on HBO) over water rights. Both the Choctaw and Chickasaw Indian nations have entered the legal proceedings. Who owns what and why always has a context. In this case, the context is something called the Treaty of Dancing Rabbit Creek which might have given the Choctaw Nation "prior and paramount" rights to and "domain" over water within a 22-county area of southeastern Oklahoma.
Sometimes the present, to make the future better, has to circle along ways into the past.
